OpenSSH RPMs for old CentOS

For some reasons I have to maintain OpenSSH up to date for CentOSs that are no longer have supports.

This openssh package has OpenSSL statically linked.

Current Version:

• OpenSSH 8.7p1
• OpenSSL 1.1.1l

Supported CentOS:

• CentOS 5
• CentOS 6
• CentOS 7

Build Requirements:

yum groupinstall -y "Development Tools"
yum install -y imake rpm-build pam-devel krb5-devel zlib-devel libXt-devel libX11-devel gtk2-devel

for CentOS5:

• Perl 5.10+ is needed (just ./configure.gnu && make && make install)
• gcc44 is prefered

Security

As OLD systems that are still on production, TOP security is hardly the first concern, while compatibility is.

This package provede the following options in /etc/ssh/sshd_config to act like the triditional version sshd.

UsePAM yes
PermitRootLogin yes
UseDNS no
